UNrrnn S'rans OHAUNOY F. KEIJLER, OF UPPER SANDUSKY, OHIO.

IMPROVEM'ENT IN RAILROAD SWITCHES.

Specification forming part of Letters Patent No. 123,482, dated February 6, 1,872.

To all whom it may concern:

Be it known that I, GHAUNCY F. KELLER, of Upper Sandusky, in the county ofVy andot, and State of Ohio, have invented a new and valuable Improvement in Railroad Switches; and I do hereby declare that the following' is a full, clear, and eXact description of the construction and operation of the same, reference being had to the annexeddrawing making a part of this speciiication and to the letters and gures of reference marked thereon.

Figure l of the drawing is a representation of a side view of my invention. Fig. 2 is a vertical transverse section. Fig. 3 is a top view ofthe same. y

This invention has relation to rail way-switch stands; and it consists in the construction and novel arrangement of devices to be employed in the raising of a notched switch-bar from its stop-pin preparatory to the adjustment of the switch. This invention also consists in the novel arrangement of a spring, which has a tendency to press down the notched switchbar, in order that the latter may the more readily and securely engage with the stop pin.

lower edge of said bar is notched at b b b, and

ts a stop-pin, b', by means of which it is held at different positions. O is a foot-plate, to be used in raising the switch-bar from the stoppin. In raisingsaid bar the block c serves as a fulcrum to it. D represents the switch-lever, pivoted to the switch-bar, and passing upward between the stand-plates. The lever D swings from side to side between the blocks d. E denotes an arm pivoted at one end to the stand A, and at the other end to the switch-lever. F is a foot-lever pivoted to the switch-stand, and connected to the arm E by a link-arm, E. By pressing down said lever the switch-bar is raised in the same manner as by pressing down on the foot-plate O. F designates a spring secured to the stand A and resting one end on the arm E. This spring may have its end slotted to embrace the switch-lever, as shown. G represents a hasp hinged to middle part of the stand A. Alock, H, is embedded in said hasp, which has an aperture in the side facing the switch-bar, to admit a staple or slotted projection, L, to the lock, in order to receive the bolt. The hasp and lock are designed for the purpose ot' securing the switch on the line of the main track. For the side tracks the notches b and stop pin b will suffice. Above the lock, in the hasp, an aperture, g, is formed, to receive a pin, g', projecting from the switch, and designed for the purpose ot' preventing the switch-bar from being raised from the stoppin. As shown in the drawing, the hasp is beveled at its lower end sufficiently to allow the hasp to fall back from the staple, but not enough to let the hasp fall down against the switch-lever. The hasp may, for a 'three-throw switch-lever, 'be hinged directly to the lever itself, and locked at the proper points to the stand A. In such cases the hasp may be constructed with a shoulder at its end to ilt under the arch ofthe stand, and thus serve the purpose ofthe pin g.

I claim as my invention- Y The hinged hasp G, containing the lock H, in combination with the switch-lever D, holding the staple or equivalent h, and the stand A, all constructed and operating substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
